Exercise alone only leads to slight wt loss, if any, but marked reduction in mortality
Adding moderate/vigorous aerobic exercise to dieting slightly increases wt loss
Aerobic exercise during wt loss lessens loss of FFM
Resistance exercise during wt loss preserves FFM and may help maintain wt loss
Any type of exercise helps maintain wt loss, but duration must be 4-10 hours/week
Compliance may be better with multiple short-bout sessions
